Poly 2- ethyl vinyl ether

The selectivity of the Complex Formation is a very interesting subject, y - Cyclodextrin, (y - CD) has been found to form inclusion complexes with poly (methyl vinyl ether) (PMVE), poly(ethyl vinyl ether) (PEVE), and poly(n- propyl vinyl ether) (PnPVE) of various molecular weights to give stoichiometric compounds in crystalline states. However, a- cyclodextrin (a - CD) and (3 - Cyclodextrin ((3- CD) did not form complexes with poly (alkyl vinyl ether)s of any molecular weight, y -CD did not form complexes with the low molecular weight analogs, such as diethyl ether and trimethylene glycol dimethyl ether.

Again, the reaction patterns exhibited the signature of carbocationic processes and again the H NMR spectrum of a poly(ethyl vinyl ether) sample exhibited an aldehyde resonance at d 9.8. [Pg.185]

Scheme 11.1 Synthesis of polystyrene-fc-poly(ethyl vinyl ether) by direct coupling.

The direct coupling of preformed living blocks (usually cation and anion or group transfer) also enables the formation of block copolymers, such as polytetrahydrofuran-b-polystyrene-b-polytetrahydrofuran [13], polystyrene-b-polytetrahydrofuran [14], polystyrene-b-poly(ethyl vinyl ether) [15], poly(methyl methacrylate)-b-polytetrahydrofuran [16], poly[0-(jS-D- glucopyranosyl)-L-serine]-b-poly(2-methyl-2-oxazoline) [8], poly(methyl methacrylate)-b-poly(butyl vinyl ether) [17], polyisobutylene-b-poly(vinyl ferrocene), and poly(vinyl ferrocene)-polyisobutylene-b-poly(vinyl ferrocene) [18]. A typical example of such a coupling process between oppositely charged macroions is presented in Scheme 11.1, for the preparation of polystyrene-b-poly(ethyl vinyl ether) [15]. [Pg.317]

Poly (ethyl vinyl ether) (PEVE) macromonomers were also prepared using initiator 5 bearing an allylic function [148]. This reactive group remained intact during the polymerization and could be transformed into the corresponding oxirane by peracid oxidation. [Pg.792]

Because initiation of vinyl ethers with HI/I2 yields polymers with extremely narrow poly-dispersities," " bifunctional vinyl ethers can be used in combination with HI/I2 to polymerize vinyl ethers and produce a,co-diiodo telechelics (Scheme 39). This method has been used to produce telechelics from ethyl vinyl ether, methyl vinyl ether and hexadecyl (cetyl) vinyl ether. Treatment of the living poly(ethyl vinyl ether) with mono- and di-amines yields telechelics with amino end groups (Scheme 39, equation 41). More jecently, telechelic poly(vinyl ether)s with terminal malonate or carboxy groups were synthesized using both a functional initiator and a functional terminator according to Scheme 40." ...

The observation in 1949 (4) that isobutyl vinyl ether (IBVE) can be polymerized with stereoregularity ushered in the stereochemical study of polymers, eventually leading to the development of stereoregular polypropylene. In fact, vinyl ethers were key monomers in the early polymer Hterature. Eor example, ethyl vinyl ether (EVE) was first polymerized in the presence of iodine in 1878 and the overall polymerization was systematically studied during the 1920s (5). There has been much academic interest in living cationic polymerization of vinyl ethers and in the unusual compatibiUty of poly(MVE) with polystyrene. [Pg.514]

Experimental studies of the adsorption of polyelectrolyte have been reported by several authors Pefferkom, Dejardin, and Varoqui (3) measured the hydrodynamic thickness of an alternating copolymer of maleic acid and ethyl vinyl ether adsorbed on the pore walls in cellulose ester filter as a function of the molecular weight and the concentration of NaCl. Robb et al. (4) studied the adsorption of carboxy methyl cellulose and poly (acrylic acid) onto surfaces of insoluble inorganic salts. However, their studies are limited to the measurements of adsorbance and the fraction of adsorbed segments. [Pg.40]
